Abstract

In a SmartZone two-way radio system, there are certain features which require that a radio user know the six-digit id number programmed into other radios. For example, a radio user can initiate a private call or page from their own radio by entering the id of the target radio. To make this more convenient, some radios have the ability to be programmed with a fixed list of radio id's and their corresponding user aliases.

INTRODUCTION

  In a SmartZone two-way radio system, there are certain features which require that a radio user know the six-digit id number programmed into other radios. For example, a radio user can initiate a private call or page from their own radio by entering the id of the target radio. To make this more convenient, some radios have the ability to be programmed with a fixed list of radio id's and their corresponding user aliases.

  Unfortunately, since this radio id list is always limited in size, radio users may find themselves una- ble to use features such as private call when the target radio id has not been programmed into their list, and they can't remember the correct id. Fur- thermore, radio users may switch radios (i.e., their normal radio is being serviced) making everyone's programmed list out-of-date.

SOLUTION

  The solution is to modify the system to provide automatic directory assistance. The initiating radio user would enter the alias of the radio user they are looking for into their radio (much easier to remem-

ber then a radio id). The, alias would be entered via the numeric keypad in the front of the radio. The radio unit then sends the request to the system via existing control channels or dedicated channels reserved for this purpose,

  At this point, the radio could be programmed to wait for the response either...
